In the U.S., the greatest source of humancaused greenhouse gas emissions is the power sector, at about 38%. The largest source of power is coal, which, even though it produces less than 40% of the power, produces over 70% of the power sector's greenhouse gas emissions.
Nuclear power contributes 20% of U.S. electricity from 99 active plants. Here's how it works, pros, cons, and the future of U.S. nuclear power.
This paper reviews operational flexibility and emissions of gas and coalfired power plants today and in the future with higher renewables. Six study cases were considered: heavy duty gas turbines in simple and combined cycle, aeroderivative gas turbines, largescale supercritical coal power plants and small and midscale subcritical coal power plants.
Pros and cons of fracking: 5 key issues By John Wihbey on May 5, 2015 Have you been asked if you support or oppose fracking? A brief guide to sorting out the plusses and minuses of key fracking issues.
Seth Godin recently posted this simplified chart, from an altogether more complicated one. He maintains that this is a simple yet nonexaggerated version of the complicated one. The point is that for each person killed by nuclear power generation, 4,000 die from coal. This is adjusted for how much
A nuclear power phaseout is the discontinuation of usage of nuclear power for energy production. Often initiated because of concerns about nuclear power, phaseouts usually include shutting down nuclear power plants and looking towards fossil fuels and renewable energy.
Electricity generation is the process of generating electric power from sources of primary energy.For electric utilities in the electric power industry, it is the first stage in the delivery of electricity to end users, the other stages being transmission, distribution, energy storage and recovery, using the pumpedstorage method.
One of the major disadvantages of coal gasification is the cost to set up and maintain the necessary facilities. The Pacific Northwest National Laboratory indicates that gasifier refractories typically last about one year to 450 days at most, costing roughly one million dollars to replace.
While coal power plants filter their emissions, trace amounts of toxic particulates penetrate air filtering systems and enter the atmosphere. Mercury is among the pollutants that enter the air from coal power plant emissions, and it can contaminate local ecological systems and harm plants, wildlife and human inhabitants.
